eth/downloader: handle missing withdrawals if empty list is expected (#26675)

This PR relaxes the block body ingress handling a bit: if block body withdrawals are missing (but expected to be empty), the body withdrawals are set to 'empty list' before being passed to upper layers. 

This fixes an issue where a block passed from EthereumJS to geth was deemed invalid.
